A tool to create and anonymize fragments from a large-scale power system model in PTI v33 format.
1. Step 1: “SDET fragment creation”
a. The original power system model (for AC power flow analysis) should be saved as a standard PTI PSSE V33 raw file, in the folder “1. SDET fragment creation”. It should be a converged power flow case.
b. Open the file “PNNL SDET_zones_fragmentation.py” and update the casename to the one to be used (line 18). Save the change to the python file.
c. Open PSS/E v33, click the button “Run Automation File” and then select the above python file
d. A number of fragments will be created automatically, based on the zone definition of the original network.
e. A number of fragments will be created with a file name of ABCDEF_ZoneX_BusnumY_GennumZ_load….raw

2. Step 2: “SDET fragment anonymization”
   a. Copy the created fragment files created at Step 1.e to a new folder containing these files, and/or other power grid models to be anonymized
   b. Go to the folder “2. SDET fragment anonymization” and open the exe file “SDET_Anonymization”
   c. Click “Select Input Folder” and select the input file folder created at Step 2.a.
   d. A list of files will be automatically shown
   e. Then Click Run button. The anonymized models will be saved in the corresponding output file folder.
   Note: the anonymization process will remove the original bus number, bus name, geographical coordinates, area number, zone number and owner information
